. CU LTIVATOR.

SPEGIFICATION forming part of Letters Patent No. 420,046, dated January28, 1890.

Application filed Augu t 10, 1889- Serial No. 320,39U. (No model.)

To all whom it may concern.-

Be it known that I, EDWIN E. EDDINGTON, of J anesville, in the county ofRock and State of \Visconsin, have invented certain new and usefulImprovements in Cultivators; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

My invention relates to an improvement in cultivators and attachmentstherefor, the object being to provide a light and easy-rum ning machinewhich maybe turned in a short space at the ends of the rows and capableof adjustment for wide or narrow rows, for working close to the plantsor farther apart, for regulating the inclination of the teeth, the depthof cut, reversing the parts that become worn by use, and renewing brokenparts and taking the machine apart or putting it together whennecessary.

With this end in view my invention consists in certain novel features ofconstruction and combinations of parts, as will be hereinafter fullydescribed, and pointed out in the claims.

In the accompanying drawings, Figures 1 and 2 are side and rearperspective views. Figs. 3, 4, 5, and 6 are detached views of parts; andFig. 7 shows the interior construction of the tooth and holder. I j a Arepresents a cross-bar, and 1 1 a pair of straps, which extend forwardfrom the ends of the bar to the rear end of the tongue or pole 2, towhich they are attached, constituting altogether the frame of themachine. Bracket-arms 3 3 depend from the ends of the cross-bar, wherethey are rigidly secured and retained in proper positions relative tothe straps by braces 4 4:- These arms are furnished with rounded sockets5 5 at their lower ends to receive and act as seats for the spindles 66, which are retained in position by a means of eyebolts 7 7, throughthe eyes of which the spindles extend, and which extend upward throughthe bracket-arms, wherein they are held and tightened or loosened bynuts 8 8. The spindles 6 6 held by the eyevbolts are adjustable endwisein order to narrow or widen the machine, and they are likewisereversible, so that in case the outer portions supported in the. wheelsbecome worn the other ends may be turned around to take their place bymerely loosening the eyebolts and turning the spindles around. Aremovable collar 9 is held on each spindle by a setscrew or other means,these collars being placed in position to confine the wheels laterally.A pin, key, nut, or other device 10 at the end holds the wheel on thespindle.

- An inveirted-U-shaped bar 11 is secured to the tongue or pole by aclip or other means 12,'and to the straps 1 1 by means of braces 13 13,and its depending ends constitute a pair ofstandards 14 14, upon whichthe holders 15 15 are loosely mounted. The drag-bars 16 16 areadjustably secured to the holders 15 15, so that they may be extendedbackward for different distances, as required. The drag-bars are eachmade in sections, the adjacent ends of which are provided with theserrated cheeks l6 16, which interlock with each other and admit of therear extensions of the bars, which carry the teeth and which are alsopreferably made in adjustable sections, being bent laterally to comecloser to or farther away from the plants to be cultivated. Not only isthis rear section of the bar capable of lateral adjustment, but the barsmay be moved from theirpoint of support, if need be; but to preventsuchmovcment the braces 17 17 are connected with the drag -bars at theirlower ends and held apart the desired distance by means of the serratedcheeks 18 .18, formed at the upper ends of the braces.

The upper or connected ends of these braces usually extend just back ofthe cross-bar A,

and a rodor link 19 extends from the bolt 20,

which holds the braces together forward to the rear end of the tongue orpole. These drag-bars are operated t-hat is, raised or-lowcred-by meansof a pair of levers 21* 21,' which are located within easy access-of therider.. Said levers 21 21 are pivoted on the posts 22 22 on the toothedsegments 23 23. Spiral springs 24 24 hold these levers back against thesegments, so that'the pawls 25 25, formed thereon, are normally retainedin engagement with the teeth, so by first forcing the handles, one orboth, toward each other until the action of the springs is overcome andthen swinging them backward or forward the drag-bars, which areconnected to the hand-levers by links 26 26, are raised'orlowered,respectively. \Vhen in the required po' sition, the springs throw thelevers toward the teeth, by which they are held securely in place. Owingto the pitch of the teeth backward, in raising the bars it is onlynecessary to pull the levers backward; but before moviug them forwardthe action of the springs must first be overcome.

A seat 28 is held on the arms 29, secured to the frame of the machinewithin easy access of the hand-levers and in convenient position for thedrivers easy control of the horses.

Different forms of teeth may be employed; but the kind whiclr Iparticularly prefer, as shown in the drawings, is provided with severalpoints to admit of being turned to use all the points, and thus serveseveral times as long as a single-pointed tooth. A toothed orradially-corrugated disk 30 is secured to the back of each tooth, and asocket plate or holder 31, provided With several interlocking radialteeth 32, is held fast to the tooth by means of a bolt 33 or similarmeans, so that the tooth may be taken 0E and changed in a moment or anew one be substituted. These socketplates are secured to the stems 34by bolts or other means 35, and the stems are held to the drag-bars atthe required inclinations in the following manner: Locking-plates 37 arepivotally secured to the drag-bars by eyebolts 38, and the stems 34extend through the eyes of these bolts, by which they are held atdi'lferent inclinations. Sockets 39 are formed in these locking-plates,and in order to throw the teeth out of line with each other some of theplates are provided with sleeves 4.0 of greater or less length, in theouter ends of which the sockets are formed. The sleeves of the frontplates preferably project toward each other, the rear ones away fromeach other, and those 'in the middle have no sleeves. Each locking-plateis provided with a toothed segment 41, which acts as a lever by whichthe plate is rocked and locked in position, and these plates are movedand secured in place by the toothed wheels 42, the teeth of which engagethe teeth of the segments. These wheels are mounted on bolts 43, so thatby simply turning them on their axes the different adjustments of thestems are effected. These wheels are flanged on' the outer face toretain the segments in place, and'they might be furnished with handlesor other means for turning them easily, if desired; or they may be madein the shape of nutsthat is, screw threaded inside to turn 011 the boltsand have an angular portion to receive a wrench, by which they may beturned. The steps 44 44: are located on the drag-bars to assist thedriver in mounting his seat; also, should it be required at any time toexert pressure upon the bars these are found convenient.

It is evident that slight changes might be resorted to in the form andarrangement of the several parts described without departing from thespirit and scope of my invention; hence I do not wish to limit myself tothe particular construction herein set forth; but,

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is
